Is the SPP E polyurethane spiral pneumatic hose suitable for continuous use at 14 bar across its full temperature range of -40Â°C to +75Â°C?

No . the SPP E polyurethane spiral pneumatic hose is rated for working pressures up to 14 bar, but that rating is conditional (âdepending on hose diameterâ) and the specification does not state that 14 bar is guaranteed across the entire temperature range. In general, polyurethane hoses can lose pressure capability at temperature extremes, and manufacturers normally specify maximum working pressure at a reference temperature (typically +20 Â°C) and reduce allowable pressure near the low and high ends. Because the description only gives a general working pressure and a broad operating temperature (-40 Â°C to +75 Â°C) without a temperatureâdependent pressure curve or explicit statement that 14 bar is valid across that full range, you cannot assume continuous use at 14 bar at all temperatures. To be certain, obtain the manufacturerâs pressure vs. temperature chart or confirm the allowable working pressure at the specific temperature and hose diameter you intend to use.

Can the SPP E polyurethane spiral pneumatic hose be used with different thread sizes or only with external BSPT fittings?

Based on the description, the SPP E polyurethane spiral pneumatic hose is finished on both ends with external BSPT threads. That means it is supplied specifically for connection to mating internal BSPT (female) fittings. Using other thread types directly would not be compatible without an adapter. So you can use different thread sizes or standards only by fitting appropriate adapters or couplings that convert the external BSPT to the desired thread type/size. Ensure adapters are rated for the hose working pressure (up to 14 bar) and suitable for pneumatic use and temperature range (-40Â°C to +75Â°C).

Does the SPP E polyurethane spiral pneumatic hose maintain flexibility and kink-resistance after repeated stretching to its maximum length?

Yes. The SPP E polyurethane spiral pneumatic hose is designed to remain flexible and resist kinking even when repeatedly stretched to its stated maximum length. Made from blue polyurethane (PUR), the material provides excellent elasticity, abrasion and tear resistance, and innate kink-resistance typical for spiral hoses. The product description specifies the stated total length is the maximum length when stretched, and the hose is engineered for pneumatic control systems, hand tools and industrial robotsâwhich require repeated extension and retractionâso it retains functional flexibility across cycles. Its working pressure (up to 14 bar, depending on diameter) and wide operating temperature range (â40 Â°C to +75 Â°C) further indicate the hose maintains mechanical integrity under typical service conditions. Proper installation and avoiding loads beyond rated pressure, temperature, or mechanical stress will help preserve its kink-resistance and flexibility over time.
